There’s a new (lord I hate the new name) thread from The Ringwatchers @Ringwatchers about the Hot Stage Load Head et al. Someone did an unroll and it’s here. I haven’t time at the moment to go over it in detail. It looks like two ring sections will be above and below, and they will be reinforced because they are irrelevant to the hot stage sieve. The Hot Stage Load Head has been reinforced in several ways; there are pictures. The assembly will go into the can crusher.

I didn’t know we had these threads on here!

Have we seen any sign that B9 has been/is being modified with the additional hot-stage ring and the new FTS ? Right now, to me this seems to be the long pole, more than the OLM.

New Booster Hot Staging section spotted earlier today. - 7/20/23 - https://starshipgazer.com

SpaceX made a prototype like this, with lots of vertical slits, and then scrapped it. It was suggested at the time that it might have been for hot staging. Well, that’s looking more likely. The current article has the outlines of the vertical slits but they haven’t been snipped out.

SpaceTwitter 5:02 PM - Jul 27, 2023:

After initial activation, a full-pressure test of the new Starship flame deflector is planned for Friday

With it is a great picture, taken from a height, of the recent test.

Static fire!

Announcements on the webcast:

• Test duration 2.74 seconds, with 4 engines shutting down prematurely.
• Vehicle and pad look good. Preparing for propellant offload.

WOW! OLM Water Deluge System conducts its first full test! That was super impressive. No more rock tornados, I’d say!

I wonder whether the MP4 will attach here? … edit: Nope, it seems not. See https://imgur.com/a/CQwvvl0 . Audio, but don’t turn it up.

Edit 2: https://www.youtube.com/watch?v=QgTqqGaU-Bg is a closer view from Starship Gazer @StarshipGazer, but with some unrelated chopstick stuff at the end apparently.

Edit 3: DRAT! I hang out in this thread, not the main group, and didn’t see that @llamacoffee had posted “[Chris Bergin - NSF] WOW! OLM Water Deluge System conducts its first full test! That was super impressive. No more rock tornados, I’d say!” here.

So B9 is at the OLM ready to be lifted. Wonder if they’ll do so today or just let it stand there.

NSF is live for today’s static fire test: https://www.youtube.com/live/UFKKFt1CQW0

Booster 9 completed a successful spin prime: https://twitter.com/SpaceX/status/1687551185509888000

I hope we see a static fire and test of the deluge system soon!

Starbase live-

1:54am- LR11000 disconnected from the y pipe

2:51am- Little crane lifts what appears to be a stand out of the pit

2:57am- What looks like a short piece of pipe is lifted into the pit

3:51am- Stand lowered into the pit

4:00am- LR11000 swings over and lowers it’s hook into the pit

4:39am- Grover lifts more rebar over for the cryo pit lid

4:50am- Another load of rebar is moved over

4:58am- 3rd load of rebar moved. That’s going to be one beefy lid

9:42am- Grover lifts what may be one of the extra deluge plate extensions over to the gap by the new stairs

9:59am- Swung back over to the side and sat down

10:07am- Grover lowers

11:14am- Concrete being cut

11:15am- Grover shows off and swings the extension plate back over to the OLM while lowered.

11:38am- Plate lowered. Lines go slack.

11:40am- Raised back up

11:47am- Lowered back down

11:57am- Picked back up and swung off to the side again

12:53pm- Generator removed from the pit

1:24pm- Basket goes up

1:31pm- LR11000 unhooks from whatever it was attached to (Most likely the Y pipe)

1:33pm- Basket goes down

2:07pm- Grover starts to remove it’s counter weights to move (Maybe to Masseys to lift B10?)

2:13pm- Grover removes more weights

2:18pm- More weights moved over to an SPMT

2:23pm- There goes another

2:24pm- LR11000 takes tension on its lifting straps

2:38pm- LR11000 lifts another deluge pipe. Grover removed 4 more weights

2:41pm- Pipe is raised higher and swung over OLM

2:48pm- Pipe starts lowering

2:58pm- Pipe is sat on the ground and the LR11000 is unhooked

2:59pm- Small crane hooks to the pipe

3:05pm- Pipe is swung over towards the left most manifold. So looks like it’s the left side of the Y. If the piece lifted early this morning was the right side, this should be the last piece to go around the OLM. Now we need the 2 feed pipes from the concrete bunker over.

3:05pm- At the same time, Grover lowers.

3:38pm- Grover drives away

4:43pm- The LR11000 drives away from the OLM

5:35pm- Small crane moves into the area that the LR11000 was sitting

7:34pm- Chopsticks lowered. Indicating all of the big lifts on the right side and behind the OLM are finished

8:04pm- Extension piece (?) lifted back over towards the OLM.

11:00pm- Pretty quiet evening from what we can see. I’m sure the welders are hard at work. I’ll be watching for more rebar to go in the pit to signify that they are done and the pipes are ready to be buried.

Tweets from Elon Musk @elonmusk.

7:51 PM - Jul 9, 2023: “3 more engines for the meaning of life.” Meaning 42 Raptor engines total for Super Heavy and Starship together. It’s with an upskirt photo of a Starship, though with 6 engines. I can’t quickly find an authoritative statement of the configuration, but since 2021, it seems that people have been stating 3 sea-level gimballing engines in the center, and 6 Rvacs (vacuum Raptors) inside the circumference (so one added between each existing pair of RVacs for a hex array). Everyday Astronaut tweeted a reply at 8:57 PM - Jul 9, 2023, “So 33 on booster, 9 on ship. Which will be the first 6 X Vac ship?”, so he seems to be thinking 6 RVacs.

The Ringwatchers @Ringwatchers have a 10-tweet thread (via threadreaderapp) analyzing it. They see a Hydraulic Power Unit: they say that, since S26 on and B9 on have the electric Thrust Vector Control system, this has to be a picture of S25. The engine shielding has been removed – for inspections? for redesign? The COPVs have been removed too. There are other details, like the interior camera, the static firing stiffeners on the RVac (vacuum Raptor) engine bells to prevent damage from sea-level flow separation, et cetera.

Two Elon tweets in sequence:

• 12:35 AM - Jul 10, 2023 “Looks like we can increase Raptor thrust by ~20% to reach 9000 tons (20 million lbs) of force at sea level”
• 12:43 AM - Jul 10, 2023 “And deliver over 200 tons of payload to a useful orbit with full & rapid reusability. 50 rockets flying every 3 days on average enables over a megaton of payload to orbit per year – enough to build a self-sustaining city on Mars.”

Edit for the record: Zack Golden @CSI_Starbase tweet on Jul 9 this picture. It showed Starship’s config as mentioned above. But the 3 center gimballing sea-level engines are lined up with 3 of the 6 RVacs on the rim, which I think would slightly reduce their range of motion.

Musk replied 10:29 PM - Jul 9, 2023

Inner engine gimbal angle is limited in some directions, due to impacting outer engine nozzle, but probably ok

1:05pm- Lifts go down at S25. Access hatch is open and vent tube installed

2:25pm- Lift back up at S25

3:38pm- Square piece of metal lifted to the top of the OLM

4:35pm- Concrete pump truck seen in background. Checked Nerdle cam and it looks like it was pouring around the high pressure tanks for the deluge earlier and now it’s over by the old landing pad.

4:40pm- Another piece of metal lifted to the top of the OLM

5:33pm- Pumper truck folds up to leave

6:12pm- Lift goes up to top of chopsticks

10:03pm- Lift at the drawworks goes down. There was definitely sparks flying like they were starting to cut something.

10:46pm- Lift was back at the drawworks shed. Looks like they tried a different method of cutting and then went back down

11:00pm- Concrete pump truck arrives at the right side of the cryo pipe pit. Time to finally pour it’s lid?

11:05pm- Pump unfolds

12:07pm- First concrete truck is at the pump and the arm folds out towards the far side of the cryo pipe trench. The lid it is.
